Be known that I, BURR C. BAKER, of Colu us, in the County of Franklin and State of 0 have invented certain new and'userovements in Advertising Mediums; o hereby declare the following to be a exact description of the same, reference ing had to the accompanying drawings, rming part of this speciication, in

e 1 represents a front view of the invent the direction of the belts carrying the a rtisements being indicated by arrows. Fig. an end view, showing spaces for stationa advertisements, and Fig. 3 a lon gitudinal v ical section, showing the mechanism for s orting and imparting motion to the belts d also the illuminating apparatus.

Si r letters of reference denote the same parts the several figures.

Th invention relates to improvements in day night advertising mediums and consists, st, of a series of endless belts adapted the advertisement-s or other matters to be hibited, and caused to travel side by side pposite directions by suitable mechanis secondly, in the peculiar construction and angenent of the mechanism for support and operatin g the belts; and, thirdly, in t combination of illuminating devices endless belts and Operating mechanams ubstantially as I will now proceed to desc 4 ln` drawings, G represents the casing or fram f the apparatus. c c' are cross-sha fts, loca respectively, at the top and at the bott of the casin B B B DD, and F are pulleys located, respectively, on

the s upper and lower shafts c c', over which the less advertising belts A A A A' A' trav The pulleys B B B are made fast to the er shaft c, while the pulleys D D on er shat't and the pulleys F F F F F ower shaft all run loose. I dvertisin g belts are seeured to cords or b E E E E E, which run in grooves in the eys, and prevent the belts from slipping the latter.

To ve the pulleys D D an opposite rotam that of the pulleys B LB B and cause the belts AJ A' to travel in are BURR o. BAKER, or COLUMBUS, OHIO.

ecification forming part of Letters Patent No. 202,2l4, dated April 9, 1878; application filed October 26,' 1,877.

verse direction from the belts A A A, cords G G are run over the central fixed pulley B', around small pulleys a a located upon each side of a cross-bar, b, below the upper series of pulleys, and thence over the pulleys D D, which latter, being loose on their shaft, are rotated in an opposite direction from the fixed pulleys.

The diameter of the pulleys B B B, as well as that of the pulleys immediately under them, is grcater than the diameter of the upper loose pulleys D D and their corresponding under ones, so that the belts Amay overlap the belts A A' without interfering with the operation of either. i

Motion is imparted to the upper shaft c by means of an endless belt or cord, K, passing around an annular shoulder on the fixed pulley B and over small guide-sheaves k Ic, and driven by a large drivin g-wheel, L. The shaft of the wheel L projects through the oasing at the rear, a'nd may be turned by a crank or connected with suitable clock mechanism, as preferred. I

From the foregoing description the operation of the device will be readily understood. When the mechanism is set in motion, the belts A A A and A' A', carrying the advertisements or other matter to be exhibited, will be, respectively, caused to move downward and upward, as indicated by arrows, Fig. 1, the effectbein g to attract the attention in a greater measure than if the belts all traveled in the same direction.

For night advertising, I arrange a lamp or candle in a suitable fixture, C, attacled, preferably, to the under side of the cross-bar b,

` within the belts, and the light shining through the belts renders the advertisements or other matters thereon plainly visible from without. The front ends of the casing are covered by -hinged glass doors, which protect the belts series of endlessbelts, earryingadvertisements or other matters to be exhibited, and caused to travel side by side in opposite directions, substantially in the manner described, and for the purpose specified.

2. The fixed puileys B B B and loose pulleys D D on the upper shaft, and the loose pulleys F F F F F on the lower shaft, combined with the cords Gc Gr and small pulleys a a for moving the advertising-belts in opposite directions, substantially as described.

3. The cords or belts E, carrying the advertising-belts, combined with the grooved supporting-pulleys, substantially as described, for the purpose specified.
